This 6 centavos brown stamp from the Philippine Islands under United States administration features the classic “Woman Harvesting Rice” design, one of the most admired allegorical images of the period. The bold O.B. overprint (“Official Business”) indicates its restricted use for government correspondence, making it more sought-after than the regular issue. Produced in the late 1920s–early 1930s, these official overprints are collected for their typographical variations and historical insight into the American colonial postal system. A clean, sharply struck overprint such as on this example enhances desirability.
